I like both images - but certainly agree that the one without light painting is more realistic to what your eye would record.
For me though personally, I am not sure if that realism is all that important in nightscapes or astrophotography. I shoot a lot of deep sky astrophotography using many multiple exposures to bring out faint objects, most of which that are absolutely never going to be visible to the naked eye. Furthermore, a number of objects are shot through narrowband filters to isolate prominent details of an object that is radiating light at wavelengths that the human eye cannot even detect. And for those images, the color palette used (that is, how one maps images shot with a particular wavelength narrowband filter to the visible spectrum) is completely arbitrary.
So just speaking for me, in a case like the images you have shown above, I have absolutely no problem with the less-realistic light painted version, (and in fact for me I prefer that version), as long as it is made clear that light painting was used, as you have obviously done here.
But it really is a personal preference thing.
As to the impact of light painters on the rest of the observers and photographers that might be arriving at a potential scene, that part is more problematic. If it were me, I would probably try to seek out more deserted areas, or if I wanted to image something more well known/closer to the road, I would not walk up and start light painting if there were others there who would be bothered by it (I would I guess ask first essentially.) Of course, in the real world, I am sure that does not always happen.
Nice set, both are fun, I do like the light painted version better, as it shows a little more context, and the light painting has been done in a very understated way that manages to add instead of detract from the sky scene.
